I actually wanted a dakimakura for a looong time but I can't find one with good design: some seem too ecchi as well, but in most cases their faces seem odd.
But this one really caught my attention, the back side is way too much for me though ;_;

Have you tried looking at unofficial ones like they sell on ebay and other sites? A good amount of them are more modest then the official ones. The one I have is one of these and the only negative about it is that the printing looks a bit fuzzy up close.
